I've just found out I'm pregnant with baby number 2. I had the most awful PND with my daughter last time,followed by a subsequent breakdown, and I've never properly healed since, even though DD is now 5. I had finally convinced myself to start on medication soon, but am now thinking not, as I'm scared of harming the baby. I'm not sleeping well at all, and I'm worried I've made a huge mistake! I want the best for everyone, but am so scared that my rashness will destroy me and my family.
